Won't that lead to a slower page load time for a lot of people due to unnecessary DNS look-ups?

- ohgodthecat 14y agoIt is a trade off and something you may want to consider depending on how you want your app/website to behave. Is that extra 300ms load a problem if it happens every five minutes? The answer will probably be no in many cases but in some it might just make the cut. The thing you can do is reduce the amount of dns requests in total like using high TTL for a cdn and have everything else served off your main site. Or if you have the option use a little bit less aggressive TTL is 1 hour downtime for an hour TTL a problem or not? Are you really going to need that instant switch of a DNS record and if you are maybe you should be looking at other ways to provide reliability.
